My experience in high education tells me that if you see shit being wiped on the walls, it's generally a sign of mental health issues - in the case of workplaces, this is definitely a sign of depression or some form of anger toward the company. When people get to the point where they literally smear their feces on the walls, they're grasping at ways to make a statement about how god-awful their environment is. Source: Our toxic geology department constantly had shit on the walls, until we completely gutted it and restructured/replaced the administration and policies. Better workplace, no more shit on the walls.
